T 0 all whomit mag/concern:

Beit'known that I, CARL BODEROK, a citi zen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain. new and useful Improvements in Banding or WindingMachines,

fully described and represented in the following specification and the accompanying drawings,.forming a part of the same.

This invention relates to improvements in winding machines, and particularly to that class of winding machines known as banding machines, the especial object of the invention being to produce a simple machine for winding a number of bands-of material (wire,

in this instance) on the work, a sufiicient number of convolutions of wire being wound to form a'band, the winding mechanism then being-moved along the work to wind bands on other portions thereof. I

Withthis obi'ect in view, the invention "port, a suitably supported carrier for't wire movable longitudinally of the work on which the wire is to be wound, and a tension devicemounted on the carrier for maintaining the wire under tension as it is drawn to and wound on the work, this tension device being so arranged as to move automatically V be in drawings, in which .line.3-3 of cal section on an enlarged sca e, of the imrelatively to the carrier and the work, so that the successive turns of each band will be laid preferably side by side.

For a better understanding of the invention, a detailed description of the same will given in connection with the accompanyigure 1 is a side elevation of a machine embodying the invention. Fig. 2 is a lan 1g. 1, certain parts being broken away. Fig. Ipartly in section, taken on the 1gs. 1 and 2. Fi 41 is a vertiroved tension device, taken on line 4- 1 of Fig. 2; and Fig. 5 is a detail sectional view of a partof the tension device, the section being taken on line 5-5 of Fig. 4.

Referring now to said drawin s,=;ill ustrating the invention in its preferre form, 1 indicates. the frame of the machine, which com ,prises two su porting standards 2, .3, one at each end of t e machine. On the standards ,2, 3 is supporteda track 4, provided .with .flanges ,5, -6, .the function of which will be hereinafter referred to, Mounted on this y of a rotatable work-sup.

track 4, atthe ends of the machine, are a tail I stock 7 and a head stock 8, secured on the track in any suitable manner, and-in which are mounted the means for supporting and also rotating the work, as for instance, an armature A, on which wire is to be handed. Tail stock 7 has at its forward end a bearing 9, in which is slidably-mounted a dead spindle 9, carrying a dead center 10 for engaging one end of the work; this bearing Qhaving a clamping device such as that usually em ployed in lathes, by which spindle 9-may be clamped against rotation, when adjusted endwise to the desired position in the tail stock. Dead spindle 9 is so adjusted in the manner usual in-lathes, that is, by means of a hand wheel 12 and a threaded spindle of the usual form (not shown) therefrom entering a threaded opening in the end of s inde 9.

In thehead stock 8 is mounte a live spindle 13, having a center 14 for engaging the work to be rotated; said spindle being rotated by gearing contained in the oil-tight casing 15in which spindle 13 is journaled in bearings 18. A face plate 16 is provided which is detachably connected to shaft 13 and carries a stud 16 for en aging a dog (not shown) on the armature an thus turning the latter as shaft 13 is rotated. The means for rotating spindle 13 during the winding or banding operation, consists of a driving shaft 17 mounted in bearings 17 (Fig. 3) in the head stock 8, and driven, from any suitable source of power (not shown), by a pulley l9 (Fig. 3), though, if desired, it may be directly driven by an electric motor or in any other suitable manner. This shaft 17 has formed thereon a worm 20 (see dotted line, Fig. 1)., which engages a worm gear 21 fast on the spindle 13, by which the latter is driven. It is desirable that the operator should be able to stop the rotation of the spindle 13.and the work at the point when a sufiicient amount of wirehas been wound on the latter to form a band, and for this purpose-the following mechanism is employed. The pulley 19, by which the shaft is driven, is loosely mounted on the shaft and is continuously rotatedfrom the source of power. This pulley 19 is cut out onone side to receive an endwisemovable clutch member 22 (shown indotted lines .in Fig. 3), which is splined to shaft 17. This-clutch member 22 is forcedinto and out-ofengagement with the pulley by a yoke shaft arm 23, .the upper end of which engages the grooved portion 24 of the hub 25 of clutch member 22. The arm 23 is fulcrumed at 26 on a bracket 27 secured to the frame of the machine, and is connected at its lower end to a link 28, this link in turn being connected to an arm 30, fast to a rock shaft 31 mounted in standards 32 and having secured to it a foot treadle 33 extending along the side of the machine. The arm 23 through link 28 and arm 30 is rocked by downward pressure on the treadle 33 to engage the clutch 22 with pulley 19 a ainst the action of a spring 34, which, when t e'treadle is released, rocks the arm 23 in the Opposite direction and disengages the clutch from the pulley, thus stopplng the rotationj'of the work support. A friction clutch 35,v 35 is preferab rotation of the work, one member 35" eing stationary and the other carriedby hub 25, these two members coming into engagement when clutch member 22 is thus moved away from pulley. 19.

The worm gear 20 and the ear 21 are, as before stated, inclosed man 0' tight case 15, which is filled with ropcr lubricating grease or oil. To enable t e operator to get at the gears for oiling or any other 1purpose, the case is provided with a removab e top portion 36, secured to the body of the casing by suitable bolts 37.

The work which is to be wound or banded with wire, which, in the instance shown, is a power armature A, is supported between" the s indies 9, 13, the centers 10, 14 of the spines being forced against the ends of the armature shaft 38. I

The means for carrying the wire used in winding or banding the work, and the means for maintainingthe wire under suitable ten sion while being drawn to the work, will now be described.

In the construction shown, there is provided a carriage consisting of a base plate 40v (see Fig. 2) extending across the machine, and side frames 41 41. The frames 41, 41 are provided with rollers 42 carried by studs or bolts 43. These rollers 42 are arranged to ride along the flanges 5, 6 of the track 4 of the machme and are, as shown (see Fi 3), flanged, as at 44, so that they will hold the carnage on the track.

The tension device which will now be described, is mounted on the carriage, so as to movewith it, and so that during the operation of winding or handing the armature or other work, it will move or swing automatically relatively to the carriage, and thus lay, the successive turns of wire properly side by side on the armature. The tension device consists of a plurality of guiding and tension sheaves supported on a wire-feeding arm 45 (see Figs. 3, 4) pivoted on a stud 46 to one of the side frames (41) of the carriage. In

the particular construction shown, there are 53 threade y employed for assisting in sto ping provided two guiding sheaves,-one (47) being ocated below the tension sheaves, and ding the-wire to the tension sheaves, an the other (48) located above the tension device and guiding the wire therefrom to the work.

The tension sheaves (five in number). are

marked 49, and are. arranged so that two of ing su port 50 movable between guides 51-.

52, an engaged at its outer end by a screw in a bracket 54 fixed to the arm 45. By turning screw 53 the support 50 and its sheave 49 may be adjusted inwardly or tion in line with that portion of the armature or other work which is to be banded with wire (the o erator in so moving the carriage,

using the andle 57 of arm 45), andthat, when the carriage is in its proper pos1t1on, with relation to the armature or other work,

the wire will be connected with the armature or other work and the latter then rotated 7 through the mechanism heretofore described, or by means of the hand wheel 16. As the o eration of banding or winding increases, t e arm 45 beingpivotally mounted on the carriage 39, will swing automatically on said carriage in the direction in which the wire is Qwoundor banded on the armature or other work, and thus cause the several turns of wire to be laid thereon successively in proper position side by side. Arm 45 is provi with an inward extension 58 carrying a spring 59 hearing against the upper edge of. t

e carriage side frame 41 (which is are shaped, as-shown), the engagement of this sprmg with the upper edge of said frame retaining arm 45 frictionally in the position to which it may be moved b the operator or to whichit is thus automatically moved. Ex-

tension 58 is also rovided with a downwardly I extending shoul er 60, and a downwardly extension Ii 61, which, engaging opposite faces of the rame 41,, aid in retainlng arm 45 in proper position with relation to the carria e, and prevent any movement thereof to or om the Work being banded as the wire is.

fed therefrom to such work.

- The wire which is to be wound on the armature is supplied from a bobbin 62 carried by an extens1on63 of the base late 40 of the carriage, this extension being ocated on the side of the machine opposite to the side on which the arm 45 is pivoted. The wire ide 64 lotension sheaves 49, and around the guiding-[sheave 48, to the armature or other work. By thus mounting the wire on the carriage, the wire supply is moved along its work with the tension device, and thus is always fed to the work in proper relation thereto.

As the end thrust on shaft 13 is considerable durin the rotation of said shaft and the armature, prefer to interpose a ball bearing 65 (see Fig. 1) between a collar 66 fast to shaft 13 and the adjacent face of the bearing 18 in which said shaft is j ournaled.
